Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances.
During a chemical change, the composition of the substance is changed. When a chemical change occurs new substances are formed through a reorganization of the atoms. A chemical change is irreversible. An example of chemical change is the fireworks explosion. Chemical Changes are also called Chemical Reactions. The chemical reaction produces one or more products, which usually have properties different from the reactants and have different physical and chemical properties.
